Any civilization that evolves during its sun’s main sequence and then finds a way to survive the red giant and supernova stages, will also probably find a way to create a Dyson sphere around the surviving white dwarf. For that reason, these stars may be more likely to host such a structure.
What’s more, a white dwarf is a better host for a Dyson sphere. The habitable zone around a white dwarf is closer to the star, so such a sphere would be smaller. A 1-meter-thick sphere built in the habitable zone around a white dwarf would require some 10^23 kilograms of matter, just a little less than the mass of our moon.

Amazon Warehouse Automation Challenge. As with everything, Amazon are cheapskates. The price money is just $25k, hardly appropriate for this. For how it is in those warehouses, check out fulfillment

For this pilot, the human driver will handle the truck on surface streets, but TuSimple is already looking to a second phase of the pilot, where the robot does all the work. Meanwhile, it’s 400-person team is working to expand the robot’s operating envelope. The system can handle high winds, night driving (handling high beams was a pain), and rain, while ice on the road remains “a nasty problem.” If it never succeeds, the postal service has a team of mules up for the task.
2020-03-20: Missed Logistics Opportunity
Suddenly the world has been thrust into a crisis with 3 interesting aspects:
- A huge upswing in demand, and delivery companies are falling way behind.
- A sudden desire to not have a delivery driver touch packages, and drivers don’t want to interact with people.
- The roads in some areas have become almost deserted due to lockdowns.
What a glorious opportunity this could have been for the road based delivery vehicles. While they have not yet reached the safety level needed to do full time operations with no human on board in regular traffic, it’s quite possible that they can do it on mostly deserted streets. Particularly if low speed operations can be tolerated on those streets. However, even if that’s true, since nobody anticipated this, nobody has worked to build proof of that level of safety.

The ability to deliver anything in an Amazon warehouse on short notice will be a very attractive product. The cost of robot delivery will be low enough to be bundled in with Amazon Prime. If you can get anything in one of those giant Amazon warehouses in 30 minutes, that’s scary news for the rest of retail.
2020-12-14: Zoox robotaxi

this is interesting from a design perspective: what assumptions are no longer true and can be revised for a better experience? Passengers face one another, allowing for a more social experience. The interior is spartan, not the overcrowded complex dashboard of current cars and some robotaxi designs. Just a small display and charging port. The seats mix taxi goals (ease of cleaning and able to handle heavy use) with car design. The electric vehicle design allows a low center of gravity, and combined with wheels moved to the corners of the vehicle, a more flexible interior design with more space for the same footprint. Each wheel can also turn independently, allowing for an 8.6m turning radius. In many cases, it will not turn at all, when it wants to change direction of travel, it just changes. The vehicle is narrow and short enough, given that, to handle streets and driveways that might be a challenge for wider vehicles. Airbags are integrated into the special seats and their enclosing walls for extra crash safety.

Outside of London is a massive supermarket—one that customers cannot enter. Instead it’s dedicated to fulfilling online orders. It’s filled with an upper-level cartesian grid swarming with over 2000 wheeled robots that zoom around in the X- and Y-axes. Beneath the robots’ wheels, each square of the grid is filled with up to 21 milk crates loaded with grocery products. The ‘bots can suck these bins up through their bottoms, then zip them over to the periphery, where additional sorting ‘bots pick-and-package them.
2023-02-23: Zoox goes public in California
Last week, the California DMV granted us our permit to operate our robotaxi autonomously on public roads. This weekend, we hit the road! It marked the first time in history that a purpose-built robotaxi—with no manual controls—drove autonomously on open public roads with passengers.
Did Neurons Evolve 2x?
On the one hand, 2 independent origins of neurons would be surprising because it seems unlikely that the precise sequence of genetic accidents that created neurons could happen more than once. But it also seems unlikely that sponges would lose something as valuable as a neuron. “The only example we know from bilaterians where the nervous system was lost completely is in parasites”

i will be extremely surprised if the swiss, world champions in NIMBYism, go through with this. would be very cool though.

hermetic builds are a thing. that’s one puzzle piece how you keep a code base with mumble millions of LOC healthy. One of the best perks of being an engineer at Google is now open source. Our build system is just awesome.

we need things like this to move on from jokes like makerbot.

enough with dumb first person shooters already. i wonder how close this concept video is to the real thing.
obsessed God
From an evolutionary perspective, the gods facilitate social bonds required for survival by raising the stakes of misconduct. Having a cosmic Wyatt Earp on the beat aids survival and reproduction by curbing others’ banditry. If you’re tempted to steal from someone, but know that God cares and has the power to do something about it, you might think twice. If God knows your thoughts, perhaps you wouldn’t even think twice. The Abrahamic God appears to be a punitive, paranoia-inducing Big Brother always watching and concerned with our crimes.
